What happens if too many of one species live in one area? 2. In your own words, define what carrying capacity is and how it affects populations. 3. List three variables that can affect the biological carrying capacity for a species. COPYRIGHT © 2016 TEXAS EDUCATION AGENCY OnTRACK Biology Journal 4. What are some food sources for sturgeon? 5. How do sturgeon survive in periods when lake fly larva are scarce? 6. What if too many sturgeon populated the lake and ate so many lake fly larva that the flies had trouble reproducing? How would the sturgeon population be affected? COPYRIGHT © 2016 TEXAS EDUCATION AGENCY OnTRACK Biology Journal 7. What would happen if another fish species, like the walleye, ate too many of the gizzard shad? How would this affect the sturgeon population? 8. Describe two ways biologists can manage Lake Winnebago to support the optimal carrying capacity for sturgeon? 9. What would happen if biologists did not control the population of sturgeon in Lake Winnebago and the number of sturgeon increased? How might this affect the population of lake flies, gizzard shad, and walleye? COPYRIGHT © 2016 TEXAS EDUCATION AGENCY
